Problem 3: A football player releases a ball with initial conditions shown in the figure. Neglect drag for this problem. a) Determine the radius of curvature of the trajectory just after release, b) Determine the radius of curvature at the apex of the trajectory c) Determine radius of curvature of the trajectory at a time 0.45 seconds before the ball reaches the peak of its trajectory. d) For each case above, compute time rate of change of speed. Assume the initial height for throw as 7 ft. V₁ = 80 ft/sec 0 = 35°
